Now he says his proposed incentive for individuals to buy insurance would allow people to "fully deduct health insurance premium payments from their tax returns."

In a way, it's similar to Rubio's proposed tax credits to buy insurance. However, Trump's plan may not be as beneficial to those with lower incomes, since they pay less in taxes.

Trump also advocates for the sale of insurance across state borders, which he argues will drive supply up and costs for citizens down. In the same vein, he pushes for allowing consumers to access drugs from overseas that have been proven safe.

As for Medicaid, Trump argues states should be allowed to allocate federal funding as they see fit. He says, "The state governments know their people best and can manage the administration of Medicaid far better without federal overhead."
